on certainty 188

188. It strikes me as if someone who doubts the existence of the earth at that time is impugning the nature of all historical evidence. And I cannot say of this latter that it is definitely correct.

yes – historical evidence – is uncertain –

and the proposition – that the earth existed at this time –

is uncertain

any proposition we operate with –

is uncertain

if you say that one proposition implies another –

then you are saying –

one uncertain proposition –

implies another –

and by the way there is nothing definite –

about implication

in propositional reality –

we operate in – and with –

uncertainty
